So North Korea launched what they claim to be a rocket taking a satellite into earths orbit (Though it's more likely an ICBM), and sources say that it failed during the first stage of launch.

More likely to be a roll of toilet tissue wrapped in tinfoil

More seriously, even if it was a failure, it was the closest thing from a rocket launch happening in North Korea since '98, and they could do a great deal of damage by deploying anti-satellite satellite/weapons (on this topic I do highly recommend to watch Pax Americana, a truly great documentary on anti-satellite weapons and the consequences they could have) even if this is unlikely. Or even the damages that a non-controlled satellite could do (ramming in other satellites and so on).
